After spray application
CAUTION:
Refer to chemical label for correct disposal of
chemical residue.
Drain out any chemical residue in the tank
through the drain tap.
Flush main tank:
1. With the main tank drained, rinse the
inside of the tank with clean fresh water.
As a guide, use 20% of the tanks volume
for flushing.
2. With fresh water in the spray tank, operate
the pump to clear chemical residue from
the lines, then open the boom valves to
allow the nozzles to be flushed.
CAUTION:
Refer to chemical label for correct disposal of
chemical residue.
Refer to chemical label for correct
decontamination procedure when
decontamination is required.
Transporting the sprayer
Make sure the vehicle has sufficient lifting and
braking capacity to carry the sprayer.
All relevant transport regulations must be
adhered to when transporting the sprayer. (ie:
speed regulations, oversize signs, flashing
light, etc.) It is the operator’s responsibility to
know the relevant regulations. Make sure the
sprayer is securely attached to the vehicle as
shown below.
CAUTION:
Take care when reversing the vehicle with the
sprayer attached. If driver visibility is restricted
use another adult, with a clear view to the rear
of the sprayer, to give reversing directions.
CAUTION:
It is the operator’s responsibility to know the
tare weight and gross weight of the sprayer.
Contact Goldacres dealer to ascertain a more
precise tare weight for your sprayer if unsure.
If any alterations are made to the sprayer, it is
the operator’s responsibility to know the tare
weight and the gross weight of the modified
sprayer at all times.
NOTE: Store the sprayer in a suitable location
to prevent freezing. If the sprayer is to be left
where freezing may occur, cover the pump
and flow meter with a material bag and empty
pump and flow meter of all water (run the
pump dry for 15-20 seconds). Make sure any
ice has thawed before using sprayer.
Ensure the main tank and any other tanks
fitted are empty.
End of Season Tasks
If the sprayer is to be stored for a long period
of time without use, there are several tasks
that need to be performed.
• Clean the sprayer thoroughly as described
under “End of Spraying Day Tasks”.
• Follow end of season storage instructions
for the engine (where fitted) as per the
engine manufacturers operator manual
supplied.
• With the sprayer attached to the carrying
vehicle, carry out a thorough observation
to determine if there is any damage to the
sprayer.
• Store the sprayer in a position where it will
not be affected by frosts, and preferably
out of direct sunlight.
• Ensure the main tank and any other tanks
fitted are empty.
Maintenance and
Troubleshooting
Pump Information (Diaphragm pumps)
The pump is critical to any sprayer
performance. Correct operation and
maintenance of the pump will ensure the
sprayer is able to perform to its capabilities.
Flushing the pump system with fresh water:
To flush the pump system, use the procedure
described under the using your sprayer
section of this manual for “Flushing”.
NOTE: Never overfill pump with oil as damage
to seals and oil bowl may result.
The pump will perform optimally operating
between 400 and 540 RPM. 500 RPM is
approximately three quarter revs on the
engine.
At lower revs excessive pulsation will occur,
while pump and diaphragm damage can result
at higher revs.
